본 발명은 수직 회전축에 의해 회전하는 풍차가 설치된 풍차실의 상부측에 발전실을 배치하여 풍력으로 발전하는 풍력발전장치에 관한 것이다.The present invention relates to a wind power generator for generating wind power by arranging a power generating chamber on an upper side of a windmill chamber in which a windmill rotating by a vertical rotating shaft is installed.

본 발명인 풍차의 회전반경이 크지 않으면서 날개의 높이를 높게하여 높은 풍력을 얻을 수 있도록 수직축에 대하여 수평 회전하는 복수개의 만곡(彎曲)된 판상날개를 방사상으로 허브(hub)에 배치한 풍차를 구성함으로서 일정한 공간의 풍차 타워 내에 여러 개의 풍차를 배치하여 지면과 공간의 이용율을 높이고 또한 풍차를 회전시키는 바람의 이용율을 보다 높이어 풍력에 의한 발전효율을 보다 향상시킬 수 있는 새로운 풍력발전장치를 개발하여 특허출원 제10-2010-0044803호로 출원하였다.In order to obtain high wind power by increasing the height of the blade without increasing the radius of rotation of the present invention, the windmill constitutes a plurality of curved plate blades that are horizontally rotated about the vertical axis in a radial direction on the hub. By developing a number of windmills in a windmill tower in a certain space, the new wind power generation device can be developed to improve the utilization rate of the ground and space, and to increase the utilization rate of the wind that rotates the windmill. The application was filed in application 10-2010-0044803.

상기한 풍력발전장치는 발전실이 풍차의 하부측에 설치되어 있기 때문에 풍차에서 발전기에 이르는 동력전달 라인이 길게 되어 그만큼 부품이 많아지고 동력전달 중에 에저니 손실이 크게 되는 문제점이 있엇다.Since the wind power generator is installed on the lower side of the windmill, the power transmission line from the windmill to the generator is long, so that there are many parts and there is a problem that the loss of power during power transmission is large.

본 발명은 회전반경이 크지 않으면서 날개의 높이를 높게 하여 높은 풍력을 얻을 수 있도록 수직의 회전축에 의해 수평 회전하는 복수개의 만곡(彎曲)된 판상날개를 방사상으로 허브(hub)에 배치한 풍차에 의한 풍력발전장치에 있어서, 풍차의 상부측에 발전실을 배치함으로서 풍차로부터 발전기에 이르는 동력전달 라인이 단축되어 그 만큼 부품이 절감되고 동력전달시에 에너지 손실이 적게 되어 풍력의 이용율이 보다 향상되는 풍력발전장치를 개발하였다.The present invention provides a windmill in which a plurality of curved plate blades that are horizontally rotated by a vertical rotation axis are radially disposed on a hub so that the height of the blade can be increased without obtaining a large rotation radius. In the wind power generation system, the power transmission line from the windmill to the generator is shortened by arranging the power generation chamber on the upper side of the windmill, thereby reducing parts and reducing energy loss during power transmission. We have developed a wind turbine.

본 발명의 목작은 풍력발전기로부터 발전기에 이르는 전달 라인이 단축되는 풍차발전장치를 제공하는데 있다.An object of the present invention is to provide a windmill generator in which a transmission line from a wind turbine to a generator is shortened.

본 발명의 다른 목적은 풍차 및 발전실의 관리가 용이하고 풍력의 이용율이 증대되는 풍력발전장치를 제공하는데 있다.Another object of the present invention is to provide a wind power generation apparatus that can easily manage a windmill and a power generation room and increase the utilization rate of wind power.

본 발명의 풍차는 수직의 회전축의 상단부와 하단부에 지지된 허부에, 폭에 비하여 길이가 상대적으로 높은 복수개의 만곡된 판상 날개가 지지대에 의해 회전축의 주위에 통풍의 공간을 두고 방사상으로 배치되어 있고 날개의 상하 가장자리에는 환상의 보강대가 결합되어 있으며, 풍차의 회전축은 발전타워의 풍차실에서 상하의 가로 프레임에 통상의 축수에 의해 회전가능하게 지지되어 있다. 회전축의 상단부에는 구동 기어가 감삽(嵌揷)되어 있다. 풍차실의 상부에 배치된 발전실에는 상기 구동기어에 연접된 복수개의 전동기어 및 회전수를 증속하거나 동력을 단속(斷續) 제어하는 제어기가 구비된 기어박스 및 DC발전기등 기본적인 발전장비가 구비되어 구성된 것이다.In the windmill of the present invention, a plurality of curved plate blades having a relatively high length compared to the width are arranged radially with a ventilation space around the rotation shaft by a support, in the upper part and the lower end supported by the vertical rotation shaft. An annular reinforcing rod is coupled to the upper and lower edges of the wing, and the rotating shaft of the windmill is rotatably supported by a normal shaft number in the upper and lower horizontal frames in the windmill chamber of the power generating tower. The drive gear is subtracted in the upper end of the rotating shaft. The power generation chamber disposed at the upper part of the windmill chamber includes a plurality of electric gears connected to the driving gear and basic power generation equipment such as a gear box and a DC generator equipped with a controller for increasing the speed or controlling the power. It is composed.

본 발명의 발전장치는 바람이 비교적 많은 해안지대, 또는 산악 고지대에 축조된 발전타워에 풍차를 설치한다. 발전실에는 발전에 소용되는 발전장비를 설치한다.The generator of the present invention installs a windmill in a power tower constructed in a coastal or mountainous highlands where wind is relatively high. In the power generation room, power generation equipment used for power generation is installed.

본 발명의 발전장치는 바람이 불면 풍력에 의해 풍차가 설정된 방향으로 회전된다. 따라서 풍차의 회전에 의해 동력을 얻게 된다. 풍차의 풍력이 전동기어에 의해 발전기에 전달되어 발전기에서 발전된다.In the power generation apparatus of the present invention, when the wind blows, the windmill is rotated by the wind. Therefore, it is powered by the rotation of the windmill. Wind power of the windmill is transmitted to the generator by the electric gear and is generated in the generator.

풍력발전장치의 발전실이 풍차실의 상부측에 배치되어 있기 때문에 풍차로부터 발전기에 이르는 전동라인이 단축되어 그만큼 부품이 절감되고 관리가 간편하며 동력의 전달중에 에너지손실이 적어 풍력의 이용율이 그만큼 증대되어 친환경적으로 풍력발전을 산업적으로 이용할 수 있다.Since the power generation chamber of the wind power generator is located on the upper side of the windmill chamber, the electric line from the windmill to the generator is shortened, so the parts are reduced, the management is simple, and the energy use rate is increased due to the low energy loss during power transmission. Therefore, it is possible to use wind power industrially in an eco-friendly way.

본 발명의 풍력발전장치는 풍차실의 상부측에 발전실이 배치되어 있기 때문에 풍차에서 발전기에 이르는 동력의 전달라인이 단축되어 취급 및 관리의 간편성과 운영의 안전성을 보다 높이고 동력손실이 적어 그만큼 풍력의 이용율이 향상되어 친환경적으로 풍력에너지를 이용할 수 있는 등 여러 가지 효과가 있다.In the wind power generator of the present invention, since the power generation chamber is disposed at the upper side of the windmill chamber, the power transmission line from the windmill to the generator is shortened, thereby increasing the convenience of handling and management and the safety of operation and reducing the power loss. The utilization rate is improved, so there are various effects such as environmentally friendly wind energy.

The blades 3 of the blades 3 are radially disposed with the space a to be vented by the support 3b around the rotary shaft 2, and the annular reinforcement 4 is coupled to the upper and lower edges of the blades 3. .

도2에 표시된 바와 같이, 풍차(1)의 회전축(2)은 철근 골조(F)로 축조된 발전타워(T)의 풍차실(6)에서 상하의 가로 프레임(f)에 통상의 축수(5)에 의해 회전가능하게 지지된 것에 있어서, 회전축(2)의 상단부에 큰기어(G1)가 감삽(嵌揷)되어 있고 풍차의 상부에 배치된 발전실(7)에는 상기 큰기어(G1)에 연접된 복수개의 전동기어(G2) 및 회전수를 증대하거나 동력을 단속(斷續) 제어하는 제어기가 구비된 기어박스(bx) 및 DC발전기(D)등 기본적인 발전장비가 구비되어 구성된 것이다.As shown in FIG. 2, the rotating shaft 2 of the windmill 1 has a normal shaft number 5 in the horizontal frame f above and below in the windmill chamber 6 of the power generating tower T constructed by the reinforcing steel frame F. As shown in FIG. Supported to be rotatably by, the large gear (G1) is subtracted in the upper end of the rotary shaft (2) and connected to the large gear (G1) in the power generation chamber (7) disposed on the upper part of the windmill. Basic power generation equipment such as a gearbox (bx) and a DC generator (D) equipped with a plurality of electric gears (G2) and a controller for increasing the number of revolutions or controlling the power interruption are provided.

이와 같이 구성된 본 발명의 발전장치는 바람이 비교적 많은 해안지대, 또는 산악 고지대에 골조(f)로 축조된 풍력발전 타워(T)의 격자형으로 구성된 풍력실(6)에 풍차(1)를 설치한다. 풍차실(6)의 상부에 배치된 발전실(7)에는 풍차의 회전력을 전달하는 기어박스(bx)와 발전기(D) 등의 발전장비를 설치한다.The generator of the present invention configured as described above installs the windmill 1 in the wind chamber 6 composed of a grid of wind power generation towers T constructed as a frame f in a coastal region or a mountainous high region where wind is relatively high. do. The power generation chamber 7 disposed above the windmill chamber 6 is provided with power generation equipment such as a gearbox bx and a generator D for transmitting the rotational force of the windmill.

바람이 불면, 풍류(風流)의 범위에 따라 풍력발전 타워(T)의 공간으로 미치는 풍력이 풍차(1)의 날개(3)의 만곡된 내면에 부딪치면서 회전력이 발생되며 날개(3)의 만곡된 내면에 부딪친 바람과 날개(3)의 만곡된 배면에 부딪친 바람의 풍압에 대한 응력의 차이로 편압이 작용하여 날개(3)의 만곡된 배면이 전진되어 일 방향으로 풍차(1)가 회전된다.When the wind blows, the wind force that strikes the space of the wind power tower T according to the range of the wind flow hits the curved inner surface of the wing 3 of the windmill 1, and a rotational force is generated, and the curve of the wing 3 is generated. Due to the difference in the stress on the wind pressure of the wind hit the inner surface and the wind bounced on the curved back surface of the wing (3), the partial pressure acts so that the curved back of the wing (3) is advanced to rotate the windmill (1) in one direction .

풍차(1)의 회전력은 회전축(2)을 통하여 발전실(7)에 전달된다. 즉, 회전축(2)의 하단부(2a)에 감삽된 구동기어(G1)가 회전되면서 이에 연접된 복수의 전동기어(G2)가 연동되고 기어박스(bx)에서 소정의 회전비로 증속회전되어 발전기(D)를 가동시키어 발전한다.The rotational force of the windmill 1 is transmitted to the power generation chamber 7 via the rotation shaft 2. That is, as the drive gear G1 superimposed on the lower end 2a of the rotating shaft 2 is rotated, a plurality of electric gears G2 connected to each other are interlocked and rotated at a predetermined rotation ratio in the gear box bx to generate a generator ( It is developed by operating D).

풍력발전장치의 발전실이 풍차실의 상부에 배치되어 있기 때문에 풍차와 발전기간에 전동라인이 단축되어 전동기구의 부품이 절감되고 전달과정에서 에너지 손실이 저감되며 근거리에서 관리취급이 보다 간편하여 친환경적으로 풍력을 이용한 발전을 산업적으로 이용할 수 있다.Since the power generation chamber of the wind power generator is located in the upper part of the windmill room, the electric line between the windmill and the generator is shortened, which reduces the parts of the electric equipment, reduces the energy loss during the transmission process, and makes the management and handling at a short distance and eco-friendly. As a result, wind power generation can be used industrially.
